Unit 3 - Energy and Matter Interacting

Front

Transverse Wave

Back

A wave whose energy moves perpendicular to the direction the wave is traveling and does not need a medium in order to travel.

Front

Longitudinal Wave

Back

A wave whose energy travels parallel to the direction the wave is traveling and needs a medium to travel through.

Front

Wavelength

Back

The distance from one point on a wave to the same point on the next wave.

Front

Frequency

Back

The number of waves in a given period. As frequency increases, wavelength decreases.

Front

Amplitude

Back

The size of a wave.

Front

Crest

Back

The highest point of a transverse wave.

Front

Trough

Back

The lowest point of a transverse wave.

Front

Compression

Back

The part of the longitudinal wave where the particles are compressed.

Front

Refraction (Longitudinal Wave)

Back

The part of the longitudinal wave where the particles are spread out.

Front

Pitch

Back

Measure of how high or low something sounds.
